I edited this question to include the Flutter community, cause a lot of you use Android Studio and if anyone knows the answer, it'll be one of you. Thanks.
The editor in Android Studio is auto wrapping lines at about 80 characters.
How can I increase this? (using version 4.0)
Cheers,
Paul
Settings > Editor > Code Style > [Language] > Wrapping and Braces > Hard wrap at
Android Studio (as with all IDEs built off of the IntelliJ platform) formats each language according to different specifications, so you will need to change this for all the languages you are using. The default is usually 100 and the max is 999
Recently the Android Studio 3.5 updates and now Android Studio 3.6, the editor window does not wrap the text so some lines are long and go off the right of the screen. I don't want to scroll left and right all the time, so would like the text to autowrap. I've read many posts on the issue but nothings has solved it.
I've tried going to
Preferences -> Editor -> General and enabling soft wraps there, but that hasn't helped.
I tried adding *.java to the soft wraps files but that didn't help.
The only thing that works is selecting View -> Active Editor - Soft Wrap. That formats the current editing window with auto wrap, but each time I open a new java file auto wrap is not enabled I would need to enable it again. This is so frustrating and was never an issue before Android Studio 3.5. Any help would be appreciated.
I had the same problem, and my solution should work for you. The delimiter in the soft-wrap file list is a semicolon, not a comma: change your comma to a semicolon.
I don't know why but sometime in Android Studio Editor, it shows vertical line as shown in screenshot below.
Don't know about other editor but it happens in Android Studio.
So why it is showing and how to hide it?
That line historically represents the margin of A4 paper, which is useful only if you need to print the code.
Old school says that you should keep your code inside that margin, to guarantee much portability.
But.. nowadays in the real life, it makes no sense to me! Because we always use advanced editors, bigger displays, and I never needed to print any single line of code.
So, if you want to do it:
Newer versions
Editor -> General -> Appearance -> Show hard wrap guide
Older versions
Editor -> General -> Appearance -> Show right margin
or
Editor -> Appearance -> Show right margin
For Mac
To remove line go to:- Preference-> Editor -> General -> Appearance -> Show hard wrap and visual guides. Uncheck it to remove.
It is as follows in the newer version of Android Studio:
Editor -> General -> Appearance -> Show hard wrap guide
im Mac
Open Android Studio and Click
cmd + ,
and follow this step:
Android Studio has changed layout again, so you can find this option at:
File -> Settings -> Editor -> General -> Appearance -> Show hard wrap and visual guides
As it is mentioned earlier, if your code is of that length, it is pretty obvious that it is not that readable, i.e. clean. Being old school, I keep it at 80 characters and spill occasionally.
How can I set a maximum length for Android Studio's code editor, or may be set a word wrap?
In my Android Studio, no matter how long a statement I type on a single line, it never automatically goes to the next line, but rather a horizontal scroll bar appears.
When I autoformat using the Ctrl+Alt+L (reference), nothing happens.
My SO or Google search found a lot of material on this for Eclipse, but not for Android Studio.
If you need not a soft wrap,
but actually, brake one long line onto several lines you need:
Go to Preferences(mac) or Settings(windows) -> Editor -> Code style -> Java/Kotlin -> Wrapping and braces (tab) -> Check "Ensure that right margin is not exceeded"
Now try to reformat your code:
press
OPTION (ALT) + CMD + L on your Mac
(or CTRL + ALT + L on PC)
Edit 13.02.19
As noted in comments this option seems not available in settings for Kotlin.
However, there is a workaround to manually add it.
Here is what it takes to make it work:
Export the settings scheme.
Open saved xml file.
Find <codeStyleSettings language="kotlin"> tag (or create)
Add the WRAP_LONG_LINES setting manually:
<codeStyleSettings language="kotlin">
...
<option name="WRAP_LONG_LINES" value="true" />
</codeStyleSettings>
Save edits and and import back the scheme.
Here you go!
MacOS:
Click on Android Studio ( left top corner )
Click Preferences
Type Code Style in search
Click on Code Style
There is a filed right to the 'Hard wrap at' - you can enter needed about of symbols you need
In File | Settings, select "Editor", then "Code Style". There is an option "Wrap when typing reaches right margin".
Edit: Just tried it, and it doesn't seem to work. Anyway, maybe the option "Use soft wrap" in the "General" group is more what you want.
#Solace, actually #Fahim Faysal's answer is quite close to what you need, but since you want to solve the problem no matter how long a statement I type on a single line, it never automatically goes to the next line, 2 more steps you need to follow:
[Step 9] type the max length you prefer at `"Hard wrap at" ()
[Step 10] change "Wrap on typing" from Default: No or No to Yes
With version 4.1.2 and with Dart language you need to go to "File/Settings/Editor/Code Style/Dart" and modify the "Line length" to the preferred number.
In Android Studio:
File->Setting->
Editor->code Style->java->Wrapping and braces(tab:right side)->keep when reformatting->Line break(make unchecked)
You can change the max column width from:
File > Settings > Editor > Code Style > Right Margin (columns)
Android Studio 3.5:
Mac -
Android Studio > Preferences > Editor > CodeStyle > HardWrap at: ____
The existing answers already answer the question in straight forward way. As a different approach you could set the style guide to kotlin style guide code style. Then if you do alt + ctrl + l as you did, you'll see auto wrap as you expected.
Just open the settings, search for kotlin and look for kotlin under code style.
On the top right hand side of the settings window you'll see Set from..., click on it.
Then on predifined style > kotlin style guide
If you'd like to follow the kotlin formatting style this could reduce more effort. For more information: https://developer.android.com/kotlin/style-guide
My Environment：
Ubuntu 18.04
AndroidStudio 3.3.2
My operate：
File -> Settings -> Editor -> Code Style
Scheme -> select Project
Hard wrap at '120'
Apply
To move the grey vertical line, that tells Android Studio where to wrap your code, go to
Settings- Editor- Code Style- Java or Kotlin- Wrapping and Braces- Hard wrap at
and enter the number of characters, where the line should be.
For dart
settings => code style => Dart => Line length
In settings/code style/kotlin/wrapping and braces replace the "do not wrap" values with "wrap if long"
You can change the Hard wrap at param
How can I change spacing in Android Studio to use tabs instead of spaces? I tried Preference -> Editor but I don't see the option there. I'm using Android Studio for Mac
Type in 'spac' in the search panel of the settings view.
You will find Editor -> Code Style->Java->Tabs and Indents->Use tab character.
This is a little weird, but others may have the same issue I did.
Yes, follow the above directions, and do the normal changes in the config file. And guess what? it looks like it's still making spaces instead of tabs, even though the settings say TABS, not spaces!
Turn on "show whitespaces" (Editor -> General -> Appearance). And then turn it off. Looks like this is enough to reset the editor so that it is now following the rules you set in the preferences.
